[0026]

Since the panel mounting structure according to the present invention has the above-described structure and operation, it has the following great effects.

(1) In the first and second inventions, since the height adjusting nut is exposed from the upper surface of the horizontal flange portion of the L-shaped lower mounting member, the height above the horizontal flange portion is increased. The adjustment nut can be operated, and the work on site can be made extremely easy. (2) In the second aspect of the invention, since the mounting brackets respectively mounted on the upper and lower panels can be mounted on the body beam through the single support bolt, the width of one panel in the lateral direction can be increased. Since it suffices to provide two mounting brackets inside, the workability can be improved and the construction cost can be reduced as compared with the conventional structure provided at four places.

(3) In the second aspect of the invention, since the horizontal flange portion of the mounting bracket for mounting the lower panel is fixed to the pedestal, the out-of-plane force of the lower panel is not transmitted to the support bolt, and this support is provided. Since it is sufficient for the bolt to bear only the out-of-plane force of the upper panel, it is possible to use a support bolt having a small cross section. (4) In the second aspect of the invention, the height adjusting nut to which the backing plate is fixed is screwed to the support bolt, and the mounting bracket can be fixed to the pedestal after the lower panel is installed. Therefore, when installing the upper panel, it suffices to insert the support bolts only into the horizontal flanges of the mounting brackets of the upper panel. Compared to the conventional structure that also inserts in four places as in the past, the construction is much more efficient. Have
